Description

Technical Field

[0001] The invention relates to the technical field of electric heating, in particular to a current-isolating fluid conveyor. Background Art

[0002] In the process of electric heating of liquid, the liquid is controlled to flow continuously through the heating area for heating. In the process of liquid supply, after the liquid flows through the electric heating structure and becomes electrified, it converts electrical energy into thermal energy through its own resistance heating, causing the liquid temperature to rise rapidly. Under the action of the tension on the surface of the support, the liquid forms a thin film, which is in direct contact with the surface of the support. By conducting the current to the liquid film, the liquid itself heats up. Liquid film electric heating is mainly suitable for processes that require large-area heating of liquids, and has the advantages of high heating efficiency, fast heating speed, and uniform temperature.

[0003] like Figure 1 As shown, the liquid electric heater includes three groups of liquid film supports 15 vertically and parallelly distributed, corresponding to the A phase, B phase and C phase of the three-phase alternating current respectively. The lower ends of the liquid film supports 15 are connected by wires to form a neutral position. A group of V-shaped confluence pools 16 are commonly arranged at the bottom of the liquid film supports 15. A group of insulating conveyors 13 are arranged directly above each group of liquid film supports 15. The top of the insulating conveyor 13 is connected to a liquid inlet pipe 11, and an outlet 14 is opened at the bottom. The top of the liquid inlet pipe 11 is commonly connected to a fluid pipe body 10. The cold fluid to be heated is input into the fluid pipe body 10, and then transported to the inside of the insulating conveyor 13 under the transmission of the liquid inlet pipe 11, and then transmitted through the insulating conveyor 13. The current is isolated inside the conveyor 13 and flows downward in one direction through the output port 14 to the corresponding liquid film support 15 at the bottom. Then the liquid forms a liquid film along the surface of the liquid film support 15 for heating, and then, under the action of gravity, it is concentrated and transferred to the confluence pool 16 for collection. At this time, the three-phase alternating current is connected. At a certain moment, the current enters the liquid film support 15 from phase A and is transmitted to the liquid film on the surface. After being connected through the wire at the lower end of the liquid film support 15 to form a neutral position and enter the B phase, the liquid film on the surface of the liquid film support 15 finally returns to the B phase. The flow direction of the current changes with the change of the three-phase alternating current. In this process, the liquid film formed by the liquid is energized and its own resistance generates heat, completing the heating process. The middle part of the bottom of the confluence pool 16 is connected to an L-shaped transfer pipe 17, and a pump body 18 is provided at the end of the transfer pipe 17. Under the action of the pump body 18, the heated liquid in the confluence pool 16 is transmitted to the next processing flow;

[0004] A control valve 12 is provided on the liquid inlet pipe 11. Under the control of the control valve 12, liquid with the same flow rate and flow rate is transported toward the inside of each group of insulating conveyors 13 to ensure that the amount of liquid transferred to the liquid film support 15 is consistent, that is, the potential between the three groups of liquid film supports 15 is kept at the same level, that is, the balance and safety when using resistance heating are ensured;

[0005] During the heating process, the liquid to be heated needs to be continuously transported toward the liquid film support 15, and high voltage is continuously applied to the liquid film support 15. In order to prevent the current from being transmitted upward along the flowing liquid and causing danger, an insulating conveyor 13 is provided to block the corresponding current upward without affecting the normal transportation of the liquid.

[0006] However, the existing insulating conveying structure, when in use, will contact different types of liquids to be heated. Over time, some impurities in the liquid will adhere to the conveyor, and some of these impurities will increase the conductivity of the conveyor. As the conductive area increases, it is easy to affect the insulation capacity of the insulating conveyor. Moreover, in the process of liquid transmission, there is a lack of filtering function for the liquid, which is not conducive to the long-term effective use of the insulating conveyor. In addition, the impurities contained in the liquid are also easy to affect the resistance balance during the subsequent heating of the heating body, thereby causing danger.

[0007] Therefore, in view of the above-mentioned problems, the present technical solution proposes a fluid conveyor that isolates current. Summary of the invention

[0011] Compared with the prior art, the invention has the following beneficial effects: by arranging the primary insulation conveying box and the secondary insulation conveying box to be spaced longitudinally, and then connecting and arranging a group of stirring type filtering mechanisms between the primary insulation conveying box and the secondary insulation conveying box, a double-layer isolation fluid current unidirectional transmission structure is formed, thereby improving safety;

[0012] By arranging a self-cleaning insulation conveying mechanism inside the primary insulation conveying box and the secondary insulation conveying box, the rotation of the self-cleaning insulation conveying mechanism is used to ensure the smooth unidirectional flow of the liquid to be heated, and at the same time, the connection of the liquid between the discharge port and the insulation swing plate is blocked to achieve insulation;

[0013] By means of a rotating cleaning assembly arranged at the end of the insulating swing plate and a one-way insulating valve inside the insulating swing plate and other structures, automatic cleaning of the insulating swing plate during rotation and automatic cleaning of the inner wall of the annular insulating bin are achieved, thereby reducing the conductive effect of impurities in the liquid on the internal structure of the primary insulating conveying box and the secondary insulating conveying box, that is, fully maintaining the insulation inside the primary insulating conveying box and the secondary insulating conveying box;

[0014] By setting up transmission belt II and transmission belt I, the operation of the stirring type filtering mechanism and the operation inside the secondary insulating conveying box are both driven by the primary connecting shaft, and the connection relationship between the structures is utilized to fully improve the operation efficiency of the asynchronous three-phase motor.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] See also Figure 1-Figure 5 A fluid conveyor is provided which isolates current, comprising two groups of primary insulating conveying boxes 130 and secondary insulating conveying boxes 131 with the same structure and arranged at intervals in the longitudinal direction, wherein the secondary insulating conveying box 131 is configured to be a proportional reduction of the primary insulating conveying box 130, and a stirring type filtering mechanism 141 is provided between the primary insulating conveying box 130 and the secondary insulating conveying box 131, wherein the stirring type filtering mechanism 141 is used to perform stirring filtering on the liquid outputted from the primary insulating conveying box 130, thereby reducing the liquid which is transferred to the upper liquid after passing through the interior of the secondary insulating conveying box 131. The impurities in the body also reduce the amount of impurities adsorbed on the internal structure of the secondary insulation conveying box 131 to a certain extent. A V-shaped liquid inlet 134 is provided on the top of the primary insulation conveying box 130. The V-shaped liquid inlet 134 is directly opposite to the bottom of the output port 14 and is used to receive the liquid to be heated discharged from the output port 14. The V-shaped liquid inlet 134 on the top of the secondary insulation conveying box 131 is connected to the bottom output end of the stirring type filtering mechanism 141, and a double-channel discharge port is provided at the bottom for two-way flow transmission as needed, and then contacting with the bottom 15 for heating;

[0031] Since the primary insulation conveying box 130 has the same structure as the secondary insulation conveying box 131, the primary insulation conveying box 130 is used as an example to illustrate the primary insulation conveying box 130. An annular insulation chamber 135 is provided inside the primary insulation conveying box 130. The top of the annular insulation chamber 135 is connected to the V-shaped liquid inlet 134, and a discharge port 136 is provided at the bottom output end. A self-cleaning insulation conveying mechanism 142 is rotatably arranged inside the annular insulation chamber 135. The self-cleaning insulation conveying mechanisms 142 between adjacent primary insulation conveying boxes 130 are coaxially connected via a primary connecting shaft 139. The outermost end of one side of the primary connecting shaft 139 is connected to an asynchronous three-phase motor 137 through an output shaft 138, that is, under the operation of the asynchronous three-phase motor 137, in conjunction with the connection of the output shaft 138 and the primary connecting shaft 139, the self-cleaning insulating conveying mechanism 142 placed inside the primary insulating conveying box 130 is driven to rotate at the same speed, that is, the liquid to be heated input into the annular insulating bin 135 is controlled to be uniformly conveyed through the discharge port 136 toward the stirring filter mechanism 141, and at the same time, the current in the bottom liquid film support 15 is prevented from being transmitted upward in reverse;

[0032] Among them, see Figure 6 The self-cleaning insulating conveying mechanism 142 includes a main shaft tube 149 rotatably arranged at the axis of the annular insulating bin 135, the end of the main shaft tube 149 is fixedly connected to the primary connecting shaft 139, and a plurality of insulating swinging plates 150 are installed at equal intervals in a ring on the circumferential outer wall of the main shaft tube 149. The end of the insulating swinging plate 150 is elastically connected with a rotating cleaning component. Under the rotation of the main shaft tube 149, the elastic connection between the rotating cleaning component and the insulating swinging plate 150 is coordinated to control the rotating cleaning component to continuously clean the circumferential inner wall of the annular insulating bin 135. The liquid input into the annular insulating bin 135 through the V-shaped liquid inlet 134 will first enter the space between the two insulating swinging plates 150 rotated to the V-shaped liquid inlet 134, and then under the rotation of the main shaft tube 149, the liquid in the space is turned over toward the discharge. The liquid is transferred to the outlet 136, and then the connection between the liquid inside the discharge outlet 136 and the insulating swing plate 150 is blocked while the gravity controls the liquid to automatically transfer downward, thereby achieving the purpose of insulation barrier. A spray-type flushing assembly is arranged between the main shaft tube 149 and the insulating swing plate 150. The spray-type flushing assembly is connected to the inside of the main shaft tube 149 with a cleaning liquid transmission channel, and the cleaning liquid transmission channel extends outward to the inside of the primary connecting shaft 139. The primary connecting shaft 139 is connected to the outside with a cleaning liquid transmission part, and the outside of the cleaning liquid transmission part is connected to the main outer delivery pipe 147 for cleaning liquid. The cleaning liquid in the main outer delivery pipe 147 for cleaning liquid is transferred to the cleaning part transmission part, and then transferred to the spray-type flushing assembly through the cleaning liquid transmission channel, and then the side of the insulating swing plate 150 is automatically flushed and cleaned;

[0033] One side of the stirring filter mechanism 141 is rotationally connected to the primary connecting shaft 139 on the adjacent side through the transmission belt II 167, that is, the operating kinetic energy of the primary connecting shaft 139 is used to drive the stirring filter mechanism 141 to rotate, stir and filter. At the same time, the adjacent secondary insulating conveying boxes 131 are coaxially connected through the secondary connecting shaft 143, and one part of the secondary connecting shaft 143 is rotationally connected to the primary connecting shaft 139 through the transmission belt I 144 upward. The kinetic energy conversion of the primary connecting shaft 139 is further used to drive the secondary connecting shaft 143 to rotate, thereby driving the self-cleaning insulating conveying mechanism 142 inside the secondary insulating conveying box 131 to operate. By setting the secondary insulating conveying box 131 and the primary insulating conveying box 130 to form a double-layer insulation, the reverse flow of current in the liquid film support 15 is fully prevented, that is, the safety during operation is increased. At the same time, the filtering function inside the stirring filter mechanism 141 is cooperated to further reduce the amount of impurities inside the secondary insulating conveying box 131, improve the insulation capacity inside the secondary insulating conveying box 131, and improve the efficiency of heating the liquid in the liquid film support 15.

[0034] In the embodiment of the present invention, the dual-channel discharge port is configured as a coaxial structure, including an inner delivery pipe 132 disposed inside and an outer output pipe 133 disposed outside the inner delivery pipe 132, and the tops of the inner delivery pipe 132 and the outer output pipe 133 are both connected to the output end at the bottom of the secondary insulation delivery box 131; since the secondary insulation delivery box 131 is a proportional reduction of the primary insulation delivery box 130, when the secondary connecting shaft 143 is driven to rotate by the transmission belt I 144, the rotation speed of the self-cleaning insulation delivery mechanism 142 inside the secondary insulation delivery box 131 is higher than the rotation speed inside the primary insulation delivery box 130, that is, the amount of liquid output from the primary insulation delivery box 130 can still be quickly and smoothly discharged downward;

[0035] The structures of each part in the technical solution are made of insulating materials or insulating layers are applied or laid on the corresponding surfaces, so as to ensure sufficient insulation capacity at each position and prevent the reverse flow of current.

[0036] In order to prevent the liquid placed between the insulating swing plates 150 from flowing out along the two sides thereof, insulating sealing strips 160 are installed on the side walls at both ends of the insulating swing plates 150. The insulating sealing strips 160 are in sealing contact with the inner wall of the annular insulating chamber 135. The insulating sealing strips 160 rotate with the spindle tube 149 and seal the two ends of the space between the two insulating swing plates 150.

[0037] In one embodiment of the present invention, see Figure 9-10The rotary cleaning assembly includes a telescopic groove 154 provided on the top of the insulating swing plate 150, and a connecting plate 155 is elastically connected to the inside of the telescopic groove 154 through a plurality of springs 156 distributed at equal intervals, and an elastic insulating cleaning plate 151 is installed on the outside of the connecting plate 155, and two rotating sleeves 157 are installed on both sides of the outer end wall of the elastic insulating cleaning plate 151, and a rotating rod 158 is rotatably connected between the rotating sleeves 157, and a plurality of rubber brushes 159 are evenly installed on the outer wall of the rotating rod 158, that is, under the rotation of the main shaft tube 149, the insulating swing plate 150 and the elastic insulating cleaning plate 151 are driven to swing synchronously, and then under the elastic action of the spring 156, the rubber brush 159 on the rotating rod 158 is controlled to contact and clean the circumferential inner wall of the annular insulating bin 135, and at the same time, the centrifugal force generated by the high-speed rotation of the elastic insulating cleaning plate 151 is used to throw off the liquid on the rubber brush 159 when it is in non-contact with the liquid, thereby fully reducing the probability of conduction;

[0038] As a preferred embodiment of the present invention, the spray-type flushing assembly includes a cleaning liquid temporary storage bin 153 provided in the middle of the insulating swing plate 150, the bottom of the cleaning liquid temporary storage bin 153 is connected to the cleaning liquid transmission channel, and one-way insulating valves 152 are evenly distributed and staggered on the outer walls of both sides of the insulating swing plate 150, and the ends of the one-way insulating valves 152 are connected to the cleaning liquid temporary storage bin 153. The cleaning liquid in the cleaning liquid temporary storage bin 153 is sprayed outward by using the one-way insulating valves 152 staggered on both sides of the insulating swing plate 150, so as to flush and clean the outer side wall of the insulating swing plate 150 on the adjacent side, that is, to ensure that the outer wall of the insulating swing plate 150 is in a clean state, to prevent the conductive impurities in the liquid from being adsorbed on its surface and weakening the insulation performance;

[0039] The one-way insulating valve 152 is made of insulating material and opens only when it is subjected to internal force, spraying the liquid in the cleaning liquid temporary storage bin 153 outward. When it is in a non-stressed state, the internal insulation of the one-way insulating valve 152 is blocked and it is in a separated state.

[0040] As a preferred embodiment of the present invention, refer to Figure 7The stirring filter mechanism 141 includes a stirring filter box 161 arranged between the V-shaped liquid inlet 134 at the top of the secondary insulation conveying box 131 and the discharge port 136 at the bottom of the primary insulation conveying box 130. The stirring filter box 161 is connected with the V-shaped liquid inlet 134 and the discharge port 136. The upper filter plate 162 and the lower filter plate 163 are plug-in installed on the upper and lower sides of the stirring filter box 161. The liquid falling through the discharge port 136 first passes through the upper filter plate 162 for primary filtration, and then passes through the lower filter plate 163 for secondary filtration. The upper filter plate 162 and the lower filter plate 163 are rotatably arranged between them. There is a stirring shaft 164, and stirring blades 165 are evenly installed on the circumferential outer wall of the stirring shaft 164. One end of the stirring shaft 164 movably passes through the stirring filter box 161 and is externally connected to a transmission shaft 166. The transmission shaft 166 is rotatably connected to the primary connecting shaft 139 through a transmission belt II 167. That is, when the primary connecting shaft 139 rotates, the stirring shaft 164 is driven to rotate under the connection of the transmission belt II 167 and the transmission shaft 166, and then the stirring blades 165 are driven to stir the liquid between the upper filter plate 162 and the lower filter plate 163, thereby improving the accuracy of filtration through the lower filter plate 163.

[0041] As a preferred embodiment of the present invention, refer to Figure 8 The cleaning liquid transmission component includes a cleaning liquid inner delivery pipe 146 opened in the first-level connecting shaft 139, one end of the cleaning liquid inner delivery pipe 146 is connected to the cleaning liquid transmission channel, the other end is closed and a static transmission ring sleeve 145 is sleeved on the outside, a liquid inlet hole is opened on the circumferential outer wall of the cleaning liquid inner delivery pipe 146, the top of the static transmission ring sleeve 145 is connected to the outside with a cleaning liquid outer main delivery pipe 147, and the bottom is connected to the cleaning liquid outer auxiliary delivery pipe 148 downward, the cleaning liquid is transmitted to the static transmission ring sleeve 145 through the cleaning liquid outer main delivery pipe 147, and then part of it is transferred to the cleaning liquid inner delivery pipe 146 through the liquid inlet hole, and the other part enters the cleaning liquid outer auxiliary delivery pipe 148, the cleaning liquid entering the cleaning liquid inner delivery pipe 146 is connected along the cleaning liquid transmission channel to enter the cleaning liquid temporary storage bin 153, and then passes through the one-way insulating valve 152 to spray and clean the outside of the insulating swing plate 150;

[0042] The cleaning liquid entering the external auxiliary delivery pipe 148 of the cleaning liquid is transferred to the static transmission ring sleeve 145 on the secondary connecting shaft 143, and then enters the cleaning liquid temporary storage bin 153 and the one-way insulating valve 152 inside the secondary insulating delivery box 131 to perform spray cleaning on the insulating swing plate 150 inside the secondary insulating delivery box 131.

[0043] The working principle of the present invention is: in the idle position of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in a sequential working order. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, the cold liquid to be heated is transported along the fluid pipe body 10, and then under the control of the liquid inlet pipe 11 and the control valve 12, the liquid is uniformly transported to the inside of the V-shaped liquid inlet 134 on the top of the three groups of primary insulation transport boxes 130. At this time, the asynchronous three-phase motor 137 is started, and the primary connecting shaft 139 is driven to rotate under the connection of the output shaft 138. At the same time, the secondary connecting shaft 143 is synchronously driven to rotate under the rotation connection of the transmission belt I 144. The primary connecting shaft 139 and the transmission belt I 144 are used to rotate the spindle tube 149 inside the primary insulating conveying box 130 and the secondary insulating conveying box 131, and then the insulating swing plate 150 is driven to separate and shift the liquid input into the V-shaped liquid inlet 134 and transmit it downward, so that the liquid in the discharge port 136 and the insulating swing plate 150 are separated. The liquid between the two is transferred separately. At the same time, when the main shaft tube 149 rotates, the rubber brush 159 at its end is driven to clean the circumferential inner wall of the annular insulating warehouse 135. At the same time, the insulating sealing strip 160 is used to contact and clean the inner wall of the annular insulating warehouse 135 to ensure the cleanliness of the inner wall of the annular insulating warehouse 135. Then, at regular intervals, the cleaning liquid is input through the cleaning liquid outer main delivery pipe 147, and then the cleaning liquid is transferred to the cleaning liquid through the cleaning liquid transmission channel under the connection of the static transmission ring sleeve 145, the cleaning liquid outer auxiliary delivery pipe 148, and the cleaning liquid inner delivery pipe 146. In the temporary storage bin 153, the side walls of the adjacent insulating swing plates 150 are spray-cleaned through the one-way insulating valve 152, and the liquid inside the annular insulating bin 135 is transferred downward to the stirring and filtering box 161. At this time, the stirring shaft 164 inside the stirring and filtering box 161 rotates under the rotation of the transmission belt II 167, stirring the liquid passing through the upper filter plate 162, and then filtering through the lower filter plate 163, and then transferred to the secondary insulating conveying box 131, and then turned over and insulated conveying is carried out again, and finally output to the outside through the internal delivery pipe 132 and the external output pipe 133.

[0044] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
